Abstract: Apparatus and methods for S-SSB transmission are provided. In an aspect, an S-SSS symbol is followed by a gap symbol. In another aspect, a first PSBCH symbol is followed by an S-SSS symbol. In a further aspect, the same MPR is used for the entire S-SSB, thus reducing/mitigating transient periods. For example, the S-SSS symbols in the S-SSB may be selected from a set of sequences having the same MPR as the S-PSS symbols. Alternatively, the MPR of the entire S-SSB may be selected based on a sequence ID of an S-SSS. In an aspect, additional symbols may be configured in the S-SSB to compensate for power reduction.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is scheduled to transmit in a first slot and a second slot after the first slot. The first UE may then transmit, to a second UE, a first set of data in the first slot based on determining that the first UE is scheduled to transmit in the first slot and the second slot. In some examples, the first UE may determine whether a power estimation capability of the second UE satisfies a threshold. In some cases, the power estimation capability may be based on a correspondence between transmissions in the first slot and expected transmissions in the second slot. Based on the power estimation capability of the second UE, the first UE transmits data in a symbol reserved for automatic gain control at the second slot.

Abstract: Methods, systems, and devices for wireless communications are described. Examples may include a receiving wireless device located in a first geographic zone receiving multiple signals from one or more transmitting wireless devices. The receiving wireless device may determine based on the received signals that the one or more transmitting devices are located in a second geographic zone. The receiving wireless device may determine configured transmit power information for each of the signals received from the transmitting wireless devices located in the second geographic zone. The receiving wireless device may estimate a path loss of wireless communications between the first geographic zone and the second geographic zone based on the configured transmit powers received in the signals. The receiving wireless device may communicate within the second geographic location based on the estimated path loss between the first geographic region and the second geographic region.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether sufficient resources are available to perform a transmission in a current slot. The UE may transmit the transmission in the current slot, transmit an early reservation signal for a future resource, or determine whether sufficient resources are available to perform the transmission in a subsequent slot based at least in part on a probability-based determination and based at least in part on whether sufficient resources are available to perform the transmission in the current slot. Numerous other aspects are provided.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The apparatus may receive from a second device a first data packet in one or more receiving slots of a time division duplex frame that includes a plurality of slots. The apparatus may determine whether the first data packet is received incorrectly. The apparatus may wait until the end of the one or more receiving slots and may transmit to the second device a first NACK in a NACK feedback symbol in a configured slot after the end of the one or more receiving slots in response to determining that the first data packet was not received correctly.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a set of resource candidates in a sidelink communication system based at least in part on a set of resource assignments for a group of other UEs in the sidelink communication system. The UE may transmit a first part of a physical sidelink control channel (PSCCH) transmission. The UE may transmit a second part of the PSCCH transmission related to the first part of the PSCCH transmission to indicate a resource candidate, of the set of resource candidates, for a transmission associated with medium access control (MAC) protocol data units (PDUs) of a particular packet. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. The method, system, and apparatus may include managing the operation mode of a user equipment in vehicle-to-everything communication. In some aspects, a user equipment may transmit an inactive request message (or a request message) to a base station to indicate the user equipment is switching from a base station scheduling mode (or a radio access network node scheduling mode) to a peer user equipment scheduling mode (or a roadside unit scheduling mode). The user equipment may receive an acknowledgment message from the base station indicating a state change to allow the peer user equipment scheduling mode. In some cases, the user equipment may receive an area identifier from the base station, and the area identifier may indicate an area where the peer user equipment scheduling mode is allowed.

Abstract: A method, a computer-readable medium, and an apparatus are provided. The apparatus communicates with a second apparatus, including transmitting or receiving a first transmission. The apparatus receives information about the second UE from a sensor at the first UE and/or from a BSM. The apparatus determines whether the first apparatus and the second apparatus are in a LOS condition based on a correlation of the information with one or more of a channel estimation, PMI feedback, or RI feedback. The apparatus may adapt a transmission parameter for a second transmission based on a predicted location of the first apparatus or the second apparatus. The transmission parameter may include at least one of a modulation, a code rate, a DMRS density, a precoder, a CSI-RS transmission periodicity or a feedback rate.
